I'm taking a critical thinking test (it's fun, btw ), and there's a question:

11. What should you NOT rely on when making a judgment call?
a. intuition
b. common sense
c. gossip
d. past experience

But what's a "judgment call"? It seems I can't grasp the stylistic nuance of this word combination.
I guess it's the same as "judgment", but in Russian we have different words for it. Does it mean it's my private opinion OR that this decision has some influence on the others? Does it imply that I'm judgemental (i.e. I'm going to criticize someone)?

PS. And what would you answer? Just curious.
